This method specifies the size, number, and alignment of blocks.
HRESULT SetProperties( ALLOCATOR_PROPERTIES* pRequest, ALLOCATOR_PROPERTIES* pActual );
[in] Requested allocator properties.
[out] Allocator properties actually set.
Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.
|E_POINTER||Null pointer argument.|
|E_NOTIMPL||Method is not supported.|
|S_OK or NOERROR||Success.|
The pRequest parameter is filled in by the caller with the requested values for the count, number, and alignment as specified by the ALLOCATOR_PROPERTIES structure. The pActual parameter is filled in by the allocator with the closest values that it can provide for the request. This method cannot be called unless the allocator has been decommitted using the IMemAllocator::Decommit method.
This method assumes that blocks are all the same size.
